INHALING APPARATUS.

Specification of Letters Patent.

Patented A r. 16, 1918.

Application filed October 4, 1915. Serial No. 53,888.

certain medicinal liquids through the respiratory organs of the luunan body for the treatment of diseases of the bronchial tubes and of the lungs. 1

Heretofore in inhaling devices the liquid is converted into a watery vapor, which owing to the aircurrent admitted, fOl'IhSdlttlB drops of water in the spraylng substance, which is undesirable and tends to clog the apparatus, and one of the objects of my 1nvention has been to overcome tlns ob ect1on.

A further object of my invention is to provide an inhaler so constructed that'the substance to be inhaled by the patient shall be a uniform vapor, which it is believed is much more effective in the treatment of the patient.

To accomplish these objects, I provide a receptacle formed of glass or other transparent material, in which is arranged a deflector into which the atomizlng current enters by means of whichany precipitation is deflected, causing any drops of the hquid which form thereon to be atomized or precipitated, so that it is possible for only the very finest spray of uniform watery vapor to leave the discharge tube.

A further object of my invention is to pro vide an apparatus which is convenient and handy to use, and which contains an atomizing chamber which admlts a flow of muform generation of the watery vapors, and provides a free and easy egress of the same.

In the accompanying drawing I have illustrated what I now consider the preferred forms of my invention, although it is obvious the size, proportion and minor details of the same may be changed without departing from the spirit thereof. In these drawings,

Figure 1 is a side elevation of the inhaler with the bulb attached thereto ready for use;

Fig. 2 is a vertical sectional view of the same.

Referring to the drawing, A represents a base or standard of any suitable construction, from which rises a receptacle A, which has formed in the top thereof an atomizing chamber B, which in Figs. 1 and 2, is shown to be of larger diameter than the receptacle A. The top of the receptacle and atomizing chamber is narrowed into min-ates in a discharge tube a.

A deflecting device B is provided in the wall of the atomizing chamber B. In Figs. 1 and 2, I have shown the deflector formed practically cup-shaped and positioned at an angle of approximately 45 from the vertical, opening toward the center of the atomizing chamber.

7) is an air or blowing tube, which is bent at right angles at approximately the center thereof, one end of which extends through the wall of the receptacle A and to which is attached a rubber tube B The upwardly extending end of this air tube inside of the atomizing chamber B, narrows to a small opening 1) directly beneath the deflector B.

Supported uponithisnir tube 7) is a vertical tube b ,'which extends nearly to the a neck a, and terbottom of the receptacle, and is alsonarrowed to a small opening at the top end thereof, 6 in proximity to the opening 7),

in the air or blowing tube. The upper end of th1s' tube extends into the atomizmg chamber. and is in line with the deflector B.

A web c connects these two tubes which togetherform a' disturber for the liquid contained in the receptacle when an air current is passed throughthe air tube in the atomizing operation,

A rubber tube B is drawn over the outer end of the air tube 6 and is held in position by frictional engagement. This tube extends to the air bulb C and from thence by a tubular connection 0', to the compression bulbC, which is of the usual construction provided with the air valve 0 in the end thereof.

The vapor may be inhaled directly from the discharge or egress opening a,.through the mouth of the patient. For certain afllictions it is more desirable, however, to inhale through the nostrils of the patient, in which case a nasal attachment is secured to the tube or discharge opening a, by means of a small rubber tubing d, which is easily attached and detached as desired. The glass tube (Z is engaged by the rubber tubing cl at one end When not in use the trils of the patient.

is closed with the discharge opening a stopper a The entire apparatus, with the exception of the rubber tubing and bulbs, is made preferably of glass, so that it is at all times sanitary and easy to keep in a samtary condition. I

The operation of the device is as follows:

A medicinal liquid E to be used is poured into the receptacle A through the tube a, which tube is left open. Pressure is applied to the compression bulb G, which forces a current of air through the air tube b. This current of air has at the same time drawn the liquid upwardly through the tube V the lower end of which tube is immersed in the liquid. charged through the opening b in the atomizing chamber, it is met by the strong air current passing through the tube b, and directed toward the wall of the deflector so that as the fluid is beingatomized by the action of the current of air, it'is forced to enter the deflector where the course of the liquid is changed, the vapor rising therefrom, and any drops of the liquid adhering are either atomized or precipitated so that only the finest spray rises in the form of vapor and is permitted to leave the atomizing chamber through the tube a.

The liquid then flows back into the receptacle and is used over again.

The body or casing of the inhaler being of glass or other transparent material, as well as the interior parts of the same, it is possible at all times to see that the apparatus is in working order without disturbing any of the parts.

I claim:

1. An inhaler comprisin a casing having formed therein a liqui receptacle and an atomizing chamber, the walls of said chamber being narrowed to a neck and terminatingin a discharge opening, an independent stat1onary deflector formed in the wall of said atomizing chamber and projectthe atomizing chamber,

As the liquid is being dis- I flector for atomizing the liquid in the receptacle and discharging the vapor therefrom through the aforesaid discharge opening.

2. In an inhaler, the combination of a liquid receptacle having an atomizing chamber in the upper art thereof, a cup-shaped deflector provide in the wall of sald chamber and extendin toward the center thereof, a liquid tube and an air tube opening into and means for forcing a current of air through said air tube into contact with the liquid rising and discharging through the liquid tube.

3. In an inhaler, the combination of a liquid receptacle having an atomizin chamber in the upper part thereof an a discharge opening, a cup-shaped deflector extending from the inner wall of said. chamber at an angle toward the center thereof, means for atomizing the liquid in proximity to said deflector whereby the precipitation is collected and discharged directly in the receptacle and the vapor rising therefrom is forced through the opening of the chamber.

4. In an inhaler, the combination of a base or standard having a transparent liquid receptacle rising therefrom, said receptacle being cup or bell shaped and having an atomizing chamber in the upper part thereof provided with a discharge opening, a cup shaped deflector formed integrally with the walls of said atomizing chamber and extending toward the center of said chamber, atomizing tubes in proximity to said deflector, and means for atomizing the liquid and deflecting the precipitation directly into-the receptacle and simultaneously expelling the vapor through the discharge opening in said chamber.

In testimony whereof I have signed this specification in the presence of two subscrib-
